Differences between Bald-Eagle and Emu

Bald-Eagle and Emu are two classes of birds that belong to the Accipitridae and Dromaiidae families respectively.

Bald Eagle is a type of Sea Eagle with two sub-species. It is a bird of prey with brown plumage and white tail. The bird is not actually bald, it has white colored feather on its head. It is characterized by yellow eyes, beak, and feet. The beak is hooked and is used for capturing the prey and preening. The bird has four toes and talons on each foot. One of the toes faces backwards and helps in holding the prey with extreme grip. According to scientists, the grip of a Bald Eagle is 10 times stronger than that of an average human’s hand. The bird also has exceptional hearing and vision. Bald Eagle is famous as the national bird of the USA.

Emu is the second largest bird in the world. It is largely depicted in Australian mythology and folklore. The bird is characterized by its long neck and legs. The legs are powerful with each foot having three forward-facing toes. The plumage of Emus is dishevelled. It is usually greyish brown with black tips for absorption of ultra violet radiation. The feathers are silky, soft, and absorb water. The tail feathers are however stiff and are used to intimidate predators. Emus are terrestrial and have small vestigial wings. Emus have exceptionally large eyes that are red with black iris. They have two eyelids – while one blinks, the other blocks dust. The beaks are short and strong. They are used for plucking rough foliage.

Where are Bald-Eagle and Emu found?

Bald Eagles live around water sources surrounded by forests. They can be found near rivers, reservoirs, lakes, and coasts. They are native to North America. They exist in Mexico, the USA, Alaska, and Canada.

Emus live in woodlands, deserts, eucalyptus forests, and regions covered with shrubs. The birds exist only in Australia. Two of their subspecies once existed in King Island and Tasmania. They are now extinct.

What do Bald-Eagle and Emu eat?

Bald Eagles chiefly eat fish. They also hunt snakes, turtles, small ducks, gulls, geese, lambs, foxes, dogs, rodents, rabbits, and crabs. These birds are also known to eat dead animals and abduct the prey from other animals.

Emus are carnivores although they primarily eat plants. The birds typically eat healthiest parts of the plants, such as fruits, berries, flowers, leaves, grains, and seeds. When accessible, they also eat insects, lizards, snakes, mice, and rodents.

Size of Bald-Eagle and Emu?

When it comes to size, The overall size of a Bald Eagle is 2.8-3.5 feet. It has a wingspan of six to eight feet.. Emus are only smaller than Ostriches. They are about 5.8 feet in height.

Bald Eagles are enormous birds. They weigh 7-15 pounds. while Emus are well-built birds. The male birds weigh about 71 pounds, while the females weigh around 81 pounds.

Where do Bald-Eagle and Emu nest?

Bald Eagles build the largest nests among all birds in the world. Known as eyries, these nests are four to five feet wide and about two feet deep. They weight up to one ton. Some nests can be double this size. They are made by interweaving sticks and branches, while soft material like grass, feathers, and moss are used inside. Nests are generally positioned on top of large trees in the vicinity of water sources. The eggs are a pale white and shaped oval. Both partners share the task of incubating the eggs for about 35 days. The young ones fledge when they are eight to 14 weeks old.

Emus nest on the ground as they cannot get on top of trees or buildings. The nests rest on the surface of the ground or in shallow craters dug up by the partners. The male Emu usually builds the nest with grass, twigs, and leaves. The nests are typically one to two meters in diameter. Emu eggs are dark green with blue spots when they are laid. They eventually turn greyish or brownish owing to exposure to sunlight. The male bird incubates the eggs continuously without food or water and loses considerable weight by the time the eggs hatch. The young ones emerge in about 56 days. The chicks of Emus are five inches tall and about 17.6 ounces in weight when they hatch. They are born with brown and white stripes that fade after three months. During this time, they will not be able to regulate their body temperature. Hence, their father takes care of them for nearly six months. The chicks stay with the father and their siblings for about one and a half years.

How long do Bald-Eagle and Emu live?

The average lifespan of Bald Eagles is 20-30 years in the wild. Their life is threatened by illegal hunting, lead poisoning, electrocution, and loss of habitat. The oldest lived Bald Eagle was 38 years old. It died in 2015 due to collision with a car.

The average age of Emus is 10-20 years in the wild. In captivity, they live up to 35 years. The oldest known lived Emu was 38 years old.

Are Bald-Eagle or Emu migratory birds?

Bald Eagles usually reside in their territories throughout the year. The ones living in Canada and Alaska travel south to spend the winters in central and southern parts of USA.

Emus are nomadic birds. Their migratory pattern depends on their location in Australia. The birds from western parts relocate to south-west in winters and north-east in summers. However, the Emus in eastern parts of the country do not migrate long distances. They do not follow a standard migratory pattern. It is understood that food sources and weather are the chief factors that drive the migration of Emus. They either migrate in pairs or in flocks.

Do Bald-Eagle and Emu fly in flocks?

A flock of Bald Eagles is called a congregation or convocation. The birds are solitary. In winters, they may roost in groups to keep themselves warm. They fly alone even during migration.

A flock of Emus is known as a mob. These birds are solitary, shy, and curious. They may also fight amongst themselves. They live alone most of the time. The exception is when they pair up during the breeding season. Also, when they have to travel in quest for new food sources, they form large flocks.

Are Bald-Eagle or Emu protected?

Bald Eagles are protected in the USA under the Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act. The laws prohibit harming and killing the birds or owning their body parts. The birds are also protected in Canada.

Emus are protected in Australia. Capturing Emus from the wild is illegal. However, they can be reared in farms with a licence. Emus are commercially bred in the country as trading of their meat, eggs, feathers, and oil is widespread.

Are Bald-Eagle or Emu endangered?

The population of Bald Eagles had declining to about 450 nesting pairs in 1960s in the USA. The bird was listed as endangered in 1978. However, the banning of DDT and other conservation efforts have yielded good results. With an increase in the numbers of Bald Eagles to about 4,500 nesting pairs in 1995, the species was re-classified as threatened. With further increase in their population to over 6,300 nesting pairs in 2000, the species has been removed from the endangered and threatened species list.

Emus exist in large populations in Australia. They are listed as species of least concern by the International Union for Conservation of Nature and Natural Resources. Emus however face several threats. Birds like eagles and hawks attack Emu chicks, while snakes and other predators steal eggs from the nest. Migrating Emus often get killed in large numbers at dog fences of agricultural lands. Further, some of them also die in road accidents. Forest fires, drought, and loss of habitat due to urbanization and claiming of forest land for cropping are other threats that these birds confront.

Can Bald-Eagle and Emu fly?

Bald Eagles fly by soaring high with the use of thermals and wind currents. They manage their speed by altering the position of their wings. During long migration, the birds rarely flap their wings in order to conserve energy. The average flying speed of Bald Eagles is 75-100 miles an hour.

Emus are flightless birds. Their bone structure does not support flying. Further, they are too heavy to lift themselves for aviation. Emus are nevertheless great sprinters. Their powerful legs, calf muscles, and toes permit them to run as fast as 30 miles an hour. They flap their wings for balance while running. Emus travel long distances in search of food and for migration. They do this on foot, covering nearly 310 miles each time. On a daily basis, the birds commute about 15 miles.

Can Bald-Eagle and Emu swim?

Bald Eagles can swim but seldom do. They are mostly airborne birds. They also dive into water to catch their prey.

Emus are not regular swimmers. However, they can swim well if they have to with the help of their strong legs. They enjoy swimming and waters. They also like to bathe by rolling themselves in shallow waters and shaking up to remove water from their soaked feathers.

Mating patterns among Bald-Eagle and Emu

Bald Eagles reach sexual maturity when they are four or five years old. During the breeding season, the birds become aggressive to defend their territory. Of their mating rituals, the prominent is the cartwheel courtship flight where the male and female soar high, lock their talons, and fall to the ground in a cartwheel spin. They also chase each other and perform aerial dances. The partners may copulate more than once a day. When the eggs are laid, both male and female take turns to incubate them for 34-36 days. The partners also share the responsibility of feeding and protecting the young ones. The eaglets are ready to fledge when they are about 12 weeks old.

Emus become sexually mature when they are 1.5 to two years old. During courtship, the male makes the first move by encircling the female with his dances and head movements. When the female accepts the proposal to mate, she strides around the male by making specific calls. The partners strut together, surround each other, dance together, tilt their heads bashfully, and flutter their feathers as part of mating. The female lays an egg per three to four days in the nest built by her partner. She generally lays 30-50 eggs each breeding season. The male incubates the eggs and takes care of the hatched chicks by feeding and protecting them.

Do Bald-Eagle and Emu mate for life?

Bald Eagles are monogamous. Not only do they mate for life, they also make caring partners and parents.

Emus are monogamous socially as they live with their partners most times of the year. However, after mating with a male and laying eggs at his nest, the female mates with new partners and lays multiple clutches of eggs at different nesting sites. During this time, her original partner carries out his duties of incubating the eggs and raising his chicks. For this reason, Emu symbolizes fatherhood in the folklore and culture of Australia.

How do Bald-Eagle and Emu sleep?

Bald Eagles roost communally during winters. They sleep on large trees to stay sheltered from severe wind and cold. During the breeding season, they sleep closer to the nests. The birds have a locking mechanism in their legs that allows them to maintain their standing posture while asleep.

Emus retire for the day after sunset. They lay down on the ground to sleep. While the younger birds stretch their neck perpendicular to the body, the adults generally fold the neck, resting it on their back. The eyes remain closed when the birds are in slumber. While asleep, Emus also arrange their feathers in a such way that if it rains, the water flows down. The birds do not sleep uninterruptedly until sunrise. They wake up once in about two hours for defecating and feeding.
